SPECSHEET
Key Features:
• Very broad 160° coverage pattern
• 60 mm (2.5 in) mid/high driver with butyl rubber surround
• 16-ohm driver, allows paralleling of multiple units on a low-Z amplifier
• Integrated backcan for easy “blind-mount” install
• Packaged with grille and C-ring support backing plate for easy installation
Description:
The Control 42C is an ultra-compact in-ceiling professional satellite
loudspeaker designed for use with the Control 40CS/T subwoofer.
When combined with the Control 40CS/T, the Control 42C offers an
extremely natural sounding and powerful subwoofer-satellite system that
is perfect for applications requiring wide bandwidth and superior sonic
performance with minimal visual impact.
The integrated backcan on the Control 42C combined with the C-ring
support backing plate allows for a quick and easy installation of the unit.
The system’s 60 mm (2.5 in) mid/high driver features a polypropylene
cone and pure butyl rubber surround for long life. The copper-clad
aluminum voice coil wound on a vented aluminum former offers low
distortion.
The 16-ohm impedance allows paralleling up to 4 speakers on a 4-ohm
capable amplifier.
The Control 42C must be operated with either an active high-pass filter
or a passive crossover, such as the one built into the Control 40CS/T
subwoofer, to protect it against damage from low frequencies.
Because of the very light weight of Control 42C, tile rails may not be
required for many in-ceiling applications. They are not packaged with
this model, however MTC-RAIL tile rail sets are available separately.
Housed in a compact package, the lightweight Control 42C features an
elegant, unobtrusive design and is ideal for both small and large projects
alike.

Continuous Pink Noise rating is IEC-shaped pink noise with a 6 dB crest factor for 100
hours continuously. Continuous Program power is a conservative expression of the
system’s ability to handle normal speech and music program material, and is defined as
3 dB above the Continous Pink Noise Rating.
